FABRIC.

No Drawing.

To all whom it may concern Be it known that I, ALFRED E. Junr, a

citizen of'the United States, residing 1n be'transpirational; which maybe r e adily caused to conform to last and other irregula'r surfaces;which shall indefinitely retain its flexibility; which shall bewater-repellent; and which in general shall possess the advantages of aplied fabric bonded by an adhesive material such as rubber cement, whiledoing away with various disadyantages of such material, particularly therelatively high cost thereof.

In manufacturing the material, preferably two layers of fabric arebrought togetheij in; superposed position and bonded under. tension by"an adhesive material which may be applied to either one or both layers.The adhesive material in its preferred form consists of the followingingredients in ap' proximately the proportions noted Dextrin 20% Glucose5%- 10% Water I. 73% 35% Castor oil 2%- 5% Totals 100%-100% In makingthe mixture the dextrin and glu- Application filed March 17, 1917.Serial No. 165,410.

is retained therein in a state of emulsion. In this connection I haveobserved that under the conditions noted dextrin has a remarkableproperty for maintaining castor and other oils in emulsified formwithout separation, for a considerable length of time. An antisepticmaterial ma be added at any time during the process 0 manufacture.

preferably em 103 for this purpose 1% of sodium bi-sul tc which has ableaching as I well as an antiseptic action. It will be observed thatalthough dextrin has been mentioned inthe composition that othercarbohydrates may be employed and that oils other than castor oil may beused.

It has been found that the article made above possesses in general thecharacteristics heretofore set forth as the objects of the invention.The material is readily conform-, able to last and other surfaces, andits flexibility remains substantiallypermanently unchanged. The materialhas been found to be more transpirational than leather. It may bereadily joined by vulcanization with. rubber since the bonding materialis not hydroscopic and hence does not prevent adhesion through steamingduring vulcanization. The material is also water-repellent.

Having thus described my invention, what I claim and desire to protectby Letters Patent is: I

1. As a new article of manufacture a plurality of layers of flexiblefibrous material joined by a flexible adhesive bond consisting of acarbohydrate, water and oil held in an emulsified condition therein.

A 2. As a new article of manufacture a plurality of layers of fabricjoined by a flexible adhesive bond consistin" of a mixture of acarbohydrate water and castor oil.

3. As a new article of manufacture a plurality of layers of fabricjoined by a flexible adhesive bond comprising dextrin, water and castoroil.
